Description
Technical field
The present invention relates to duct pieces of shield tunnel technical field of construction, the section of jurisdiction for referring in particular to a kind of class rectangle shield tunnel connects
Binding structure and its construction method.
Background technology
The section of jurisdiction of shield structure is that mutual splicing assembles, during pipe sheet assembling, connecing between section of jurisdiction and section of jurisdiction
Head position is the weak spot of total stress, and due to the section of jurisdiction of class rectangle, its sectional span is larger, thus after being completed
The external loads that section of jurisdiction is born are larger.In current conventional duct pieces of shield tunnel seam arrangements, lining cutting connecting bolt to section of jurisdiction
The distance of anchor ring is identical, still, due to the moment of flexure size that each position in domain section of jurisdiction is subject to be it is different, therefore, existing section of jurisdiction
Seam arrangements can't reach good structural-load-carrying capacity.Moreover, the adjacent section of jurisdiction in existing concrete shield tunnel
The anchor ring of piecemeal is substantially that face is directly contacted with face, when tunnel duct piece because the Water And Earth Pressures effect of surrounding produces stress bending
When, or tunnel duct piece, when the assembled process of construction produces stress concentration, the corner of adjacent section of jurisdiction piecemeal is easily mutually collided
And cause breakage.
